The hiking route to peak will be better being started at 6 in the morning because you can enjoy the beautiful scenery of Mount Argopuro and also will better if you hire a guide or a porter that will help you language. You can pay above 35,000 rupiahs for per person each day including their catering. From Baderan, you can start to hike to the Second Spring (Mata Air Kedua), the distance is 6.5 km and it takes 6 hours, then you can spend the night around the Second Spring. If you are strong enough, it will be better if you go straight to Sikasur (it is above 8.5 km from the Second Spring) and you can spend the night over there. Then you can continue your hiking to Rengganis Peak and it takes about 5 hours.
It will be better if you do not spend the night on the peak because of the very cold weather and the extreme wind velocity. After reaching the peak, you can return to Sikasur and spend the night there and the next day you can return to Baderan before coming back to Pasir Putih.
